SELF-WINDING MEANS FOR SHADE ROLLERS.

Application filed May 1, 1923.

To all whom it may concern:

Be it known that I, ALASTA ANDERSON, a citizen of the United States, residing at Troy, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Self-Winding Means for Shade Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to shade rollers and more particularly to means whereby the shade or curtain may be automatically wound upon the roller in substantially the same manner as the ordinary spring roller.

The principal object of the invention is the provision of a fixture which may be applied to any shade roller whereby to convert the same into a spring roller for winding the shade thereon in the usual way.

Other objects and advantages will be apparent and suggest themselves as the-nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements,various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application.

Figure l is a sectional detail View of the shade roller attached and an end portion of a shade roller in cooperative relation therewith,

Figure 2 is a side View of the spring and drum removed from the bracket,

Figure 3 is a detail view of the bracket and dog carrying plate attached thereto, with the dog and journal cooperating therewith,

Figure a is a detail view of the journal, the cap plate being open, and

Figure 5 is a detail View of a modification.

Corresponding and like parts are referred to in the foilowing description and designated in the several views of the. drawings by like reference characters.

The numeral 1 designates a shade roller which, in accordance with the presentinvention, has opposite end portions reduced 3 as indicated at 2, and preferably of non- Serial No. 635,984.

circular form in cross section. It is preferred to have the reduced end 2 of triangular form, although such outline is not essential. A journal is fitted to the reduced end 2 and comprises a trunnion 3 and a socket 4, the latter receiving the reduced end 2 and having a side closed by means of a cap plate 5 which is hinged so as to swing into open or closed position, suitable fastening means being provided to secure the cap plate. when closed. Recesses 6 are formed in the sides of the trunnion 3 to coact with the dog, whereby the shade or curtain is held in the required adjusted position.

A spring 7 of the spiral type, such as employed in clocks, is arranged within a drum 8 and is secured at its outer end to the rim thereof and is provided at its inner end with a pin 9 having a projecting end 10 of IlOll-CliClllill form to enter the trunnion 3, whereby to cause the pin 9 and journal to rotate in unison.

A casing 11 receives the drum 8 and closes the open side thereof and is centrally apertlu'ed to receive the journal. A plate 12 is secured within the casing 11 and is provided with dogs 13 which are pivoted thereto, said dogs being disposed to coact with the recesses 6 in a well known manner to hold the shade or curtain in the required adjusted position. The casing 11 is provided with cars 14 whereby to receive fastenings to admit of attaching the fixture to a window frame or other part.

It is proposed to provide each end of the shade roller with a fixture substantially as herein indicated but in some instances, one end of the roller may be provided with a pintle 15 to coact with a bracket 16 having a pintle receiving slot, such arrangement being indicated in Figure 5.

lVhat is claimed is:

A journal of the class described comprising a trunnion having means for coa-ction with an escapement pawl, a socket adapted for reception of a roller trunnion, said socket being open at a side thereof, and a cap carried by the socket and movable with respect thereto normally closing said opening, said cap being adapted to be opened to expose the opening for removal of the roller trunnion.

In testimony whereof I afiix my signature.

ALASTA ANDERSON.
